The Cooler Master CM310 is mainly targeted at casual gamers who don't want to spend a lot of money on a mouse, but still want something of higher quality. The mouse is made out of great materials, doesn't feel cheap, and is sturdier than some way more expensive mice out there. The surface coating is nice and grippy, especially on the sides, where it's equipped with textured rubber panels. It weighs about 100 grams and should in my opinion be a bit lighter, but this mouse most probably won't see much low-sensitivity action on an enormous mouse pad. As for its dimensions, it will in my opinion mostly fit claw and palm grippers with hands between 16 and 20 cm; however, this is as always entirely up to personal preference.

I would love to call the sensor's performance great, but I can only call it decent compared to the competition in this price range. The PMW3325 itself is a good sensor, but for some reason, the CM310 has some smoothing added to it, and there's a minor amount of angle snapping as well. This results in about 2-3 ms of latency on sensor movement. The latency most probably won't be detectable by those users this mouse is catering to, but I wouldn't really advise using it for competitive gaming. Unfortunately, the CPI steps are pre-defined, and there's no way to add custom CPI values, and the polling rate is fixed to 1000 Hz as well; there's no possibility to adjust it.

Moving on to the buttons, they feel pretty great. The main ones are a tad mushy, but there is not much unnecessary travel, and they are still spammable—their switches are rated for 30 million clicks too, which is a bit above the norm. Scrolling is great with the CM310. It's tactile and light, and the same goes for the remaining buttons. Unfortunately, click latency is a tad high on this mouse. I hope CM will fix this soon with a firmware update.

Mouse feet on the CM310 are really good. They are out of their league as they actually feel a lot smoother and faster than most skates on mice that cost more than double the price. Unfortunately, there are no replacement sets provided in the package. As for the cable, it's not as great. It's rather thick and stiff and generates quite a lot of resistance—affixing it in place with a bungee or something similar is highly recommended.

RGB lighting has both the scroll wheel and rear CM logo light up according to the set CPI level, while some LED lines run across the shell, and these can have various different effects as well.

After the minor flaws and quirks, do I still recommend this mouse? It depends on the user's preferences. If you want to play competitively, this mouse might not be your optimal choice. For serious use, especially FPS, MOBA, RTS, and other fast-paced, latency-sensitive competitive online games, you should definitely go for something higher class. If you want to play casually or are not even a gamer and just find the shape and specs ideal for your needs, it can be the perfect choice. For $29.99, it's not a huge bang for the buck, but still a good deal—if you get one on sale, it's an even better one.
